    Design of a Pressure Vessel Lid Requirements

    Thanks JStephen. More information here. So the pressure of 750 of water is LIMITED. The supply is very small, maybe 1 quart or liter of water to supply the internal pressure of 750 psi inside the vessel. The vessel has been used in this application up to 900 PSI filled with water.

    Design of a Pressure Vessel Lid Requirements

    Hi LittleInch, Thanks for the information. So the existing pressure vessel is custom designed and built many years ago, there is no code on it that it was made to. They are calling it a lid because there currently is a custom designed lid on it right now, hence why the 36 holes. Cant find any...

    Design of a Pressure Vessel Lid Requirements

    Hello, There is an existing pressure vessel used for pressure testing that is filled with water and brought to pressure. I need to design a lid that would handle internal pressure (filled with water) of 750 PSI max. The construction will be made out of steel plate, A36. The diameter of the lid...

    Thanks Tugboat.. very helpful. I found this comparison between C10100 vs C11000 and it looks to be identical material. I believe either should work for the application...

    Hello, I have a small copper bar (.5"x.75"x6") that is used for water flow, and get soldered to small tubes, almost like a main water valve that distributes water to smaller tubes along the copper bar. The part is originally made from C110 copper bar. A manufacturer is quoting to make it out of...

    Choose Steel Type for High Temperature Furnace

    Ed, Thanks for the info. Yes, there will be air in the furnace, it is actually a temperature chamber. More like an oven. Oxidation wont hurt the parts, they will only be used a few times before retiring. No strength needed. One tool is a pressure cap that will be seeing 300psi at 850F temp...

    Choose Steel Type for High Temperature Furnace

    I am designing a tool that will go into a heat furnace at 850F degrees for 30 minutes, and need to decide what grade steel to make the tool out of. I was originally thinking 304 or 316SS due to its high temperature properties, but cost is significantly more than A36 or a low carbon steel. Trying...
